IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Stem cell factor (SCF), also known as mast cell growth factor (MGF), KIT-ligand and Steel Factor, is a cytokine that binds to the c-KIT receptor (CD117). SCF can exist both as a transmembrane protein and a soluble protein. SCF plays an important role in hematopoiesis, spermatogenesis, and melanogenesis. SCF plays an important role in the hematopoiesis during embryonic development. Sites where hematopoiesis takes place, such as the fetal liver and bone marrow, all express SCF. Mice that do not express SCF die in utero from severe anemia. Mice that do not express the receptor for SCF (c-KIT) also die from anemia. SCF may serve as guidance cues that direct hematopoietic stem cells (HSCs) to their microenvironment in which a stem cell resides and it plays an important role in HSC maintenance. Diseases associated with KITLG include hyperpigmentation, familial progressive, 2 and testicular non seminomatous germ cell tumor.
